Referring to the drawings and particularly to Fig. 1, the slicer comprises generally a, frame indicated at that is supported on a plurality of feet 25. This frame includes sides, ends and numerous cross braces, most of which have been omitted for purposes of clarity and only those framing memberswhich are deemed to be important for a full disclosure of the invention are shown. This frame includes a pair of cross braces 21 (Fig. 1) that are -spaced longitudinally along the frame 25 and are welded or otherwise secured to the sides of the frame. Supported on these cross braces 21 are spaced bearing blocks 28, there being one of such bearingV blocks at each end of each cross brace 21. Mounted on these bearing blocks 21 is an inverted U-shaped frame generally indicated at 29 (Fig. 2) that is provided with spaced vertically disposed legs, one of which is shown at 30 in Fig. 1. The bot- `tom. of each inverted leg 30 is provided with a foot portion 3| that provides a forwardly and rearwardly projecting bearing plate 32, each of which is mounted for sliding movement on the corresponding bearing block 28. Thus the U- ushaped frame 29 is adapted to slide back and forth on the bearing blocks 28 in a direction from left to right and return as shown in Fig. 1.

Each leg 3U is provided with a vertical slot formed between spaced upper and spaced lower bearing members 33, in each of which vertical slots is mounted a plate 34 that is adapted to reciprocate vertically between the bearing mem- *bers 33. .bearing members 33 against longitudinal move- This slidable plate 34 is Xed by the ment with respect to the U-shaped frame 29.

`Mounted on the lower yend of each of the plates 34 is a lug 35. An upstanding bearing member 35 (see Figs. l and 3) is disposed at each side of the frame 25 .and a shaft 31 is journalled at its opposite ends in these spaced bearing members 35. An arm 38 on each side of the machine is pivotally mounted adjacent to its lower end on the shaft 31 and is bifuroated on its upper end so as to receive the lug 35 between its furcations. "Also journalled in the spaced upright bearing members 36 is a shaft 39 (see Figs. 1 and 3) on which is mounted a drive sprocket wheel 49 (see Figs. 3 and 7) about which operates a ,sprocket chain 4l that is powered from a suitable motor (not shown). Gear reduction facilities may be provided in this motor drive if desired, and as shown in Fig. 7 in order to take up and adjust the slack in the sprocket chain 4| an idler pulley 42 may be provided, the adjustment rocating motion of the sliding plates 34 in a manner to be presently described. The other face of the cam member 45 is provided with a cam track 41 that transforms rotary motion of the shaft 39 into reciprocating motion of the U- shaped frame 29 in a manner also to be presently described.

Again referring to Fig. 1 a shaft 48 is journalled in the spaced upright bearing members ,36

CII

'as to similarly rotate the foot 13.

and mounted on this shaft adjacent each end thereof is an arm 49 that at one end is keyed or otherwise xed to the shaft. The other end of each arm 49 is provided with an elongated slot 49a in which the lug 35 on the bottom of the plate 34 is adapted to slidingly fit.

Referringfnow to Fig. 8 the cam track 46 in the cam member 45 is formed by and between a central cam boss 5B and a marginal ange 5| that is spaced from the cam boss 50. A cam follower 5| rides in the cam track 45 and this cam follower is mounted on the end of an arm 52 that is keyed as at 53 to the shaft 48. Thus as the cam member 45 rotates the cam follower 5| riding in the cam' track 45 transmits backward and forward rotary motion to the shaft 48. Referring now to Fig. 1 this backward and forward rotaryV motion of the shaft 48 transmits similar rotational reciprocating movement of the arm' 49 so as to raise and lower the corresponding sliding plate 34 on each leg 3U of the'U-shaped frame 29.

Again referring to Fig. 8 the cam track 41 on the opposite face of the cam member 45 is provided with a follower 54 that rides in the track. This cam follower 54 is mounted on the end of an arm 55 that is mounted on the shaft 31 at its opposite end and is keyed or otherwise secured to the shaft as indicated at 56. Thus as the shaft 39 rotates the motion of the follower 54 is transmitted to the shaft 31 in the form of back and forth rocking motion. Referring to Fig. 1 this movement of shaft 31 is conveyed from each arm 38 to the lug 35 thereby transmitting horizontal reciprocating movement to the U-shaped frame 29.

Referring now to Figs. 3 and 7 an over-riding clutch 51 is mounted on the shaft 39, the clutch being adapted to transmit rotary motion of the drive sprocket 40 to the shaft 39. This clutch 51 may be a conventional over-riding clutch and for purposes of illustration comprises a driving clutch member 58 that is powered directly by the sprocket wheel 40 and a driven clutch member 59 that is pinned or otherwise secured to the shaft 39. The peripheral face of the driven clutch member 59 (see Fig. 7) is cammed as indicated at 6U so as to provide a stop or shoulder 6|. An arm 62 pivoted at its lower end at 63 to a part of the frame 25 is provided at its upper end with a follower 64. Thus as the shaft 39 rotates in the direction of the arrow indicated at 65 the follower 64 riding along the cammed peripheral surface of the driven clutch member 59 engagesfthe shoulder or stop 6|, so as to stop the rotation of the driven member 59. A tensionv spring 66 spring biases the arm 62 to a position against the cammed surface of the driven clutch member 59. A locking arm E1 is pivoted at 68 to the arm 62 and is provided with a locking head 69 that engages a shoulder member 10 that is disposed on the periphery of the driving clutch member 58 (Figs. 3 and 7). The function of this locking head 69 is to prevent backward rotation of the driving clutch member 58 as the result of bouncing off the follower 64 when the driving clutch member 58 is suddenly brought to rest. An operating handle 1| is pivoted on a shaft 12 mounted on the frame 25. Shaft 12 is provided with a foot 13 that is fixed adjacent to an arm 14 (Fig. 7).. This operating handle 1|. is adapted to rotate back and forth about its pivot point 12. so This foot 13 engages an arm.14 that is fixed to the pivoted arm 62 so Vthat when the operating` handle 1| is p ovide'd-"at the ppsitefnds 0f the bellicrank' I, freeeramis sajsevir'i'sto connect each' knife-as "senblyt'o the "corresponding end of' the bell 'crank 9 ,I Each of these rocker arms''fis `-more"erless 'triangular'in 's'hapef"and is respectively 4pivotally moimtedat itsT apex as atY 95 toar'mil'ldi Aand one"A I"endf ofl rrran 'extendable link sie, thelatter vxof 'which Vis :pivotall'y l'oonn'ected'at itsl other -ren'd to arm 'lb'offthebell crank SI. l

Each of the'rocker 'arms 94 'is pivotally mounted `cna-shaft `98 that is carriedby sliding plate 34. At the opposite-side of the device is 'ja vlink99 that is disposed oppsiteieach rocker arm 94'and each of such links 99 ispivoted at itscen- 'teras indicated at I'Ilil to the adjaeentpla'ted.

The'drum rI I8 `is-preferably provided with'a rubberized treated peripheral surface so as to vprovide traction for'the-belts II'I- that pass over the surface of this drum.

YReferring to Figs. 5 and-6, as above mentioned vthe rollers IIZ and IIS in each 'instance are journalled in the vertically disposed legs liofthe 'U- frame 29 so that as theU-frame Eil-moves back and forth the rollers IIEfand I IBY'tra-vel with the The rollers I'II, H4, Ileand IIe-and the drum I I8 on the other hand-'are montedfbetween the iixed side frame members I-IiB `(see Fig. 2) so that the axes of these rollers in each invstance are stationary. lThus thev distances wbe- `tween the rollers II 2 and 'I I3 onthe one hand and the remaining rollers on the otherfvary dur- "ing the movement of the U-frameZS.

It is to be'noted in Figs. 5 and-6, that' inthe case ofA ther discharge conveyor unitV I Ib disposed to the right of'theknife blades 96, a guide block II2a is carried by legs-3 (Fig.`3) and itis employedinstead of roller II2. Thisgui'de block I I 2a inrther serves:tliejsamefpurposeasthe roller I I 2 but A'eX-tends Vcloser tothe `knife 96" than"I4 the accepte roller 112 and hence provides better supportv for the cut candy bars. The remainder of conveyor unit 1101) is identical with conveyor Illia.

As shown in Fig. 2 each shaft 119 projects through one of the upright frame members |138 and has a sprocket wheel 120 fixed to the end thereof. A sprocket chain 121 operates about Aeach pair of upper and lower sprocket wheels |213 that are mounted on each set of upper and lower drum shafts 119. The lower shaft 119 projects through the opposite upright frame member 108 and is provided with a sprocket wheel |22 that is powered by a sprocket chain 123 that passes over a sprocket wheel 124 (Fig. l) that is mounted on a shaft 125, this shaft being journalled between the upright bearing members 35. The drive chain 123 as indicated in Fig. l passes over sprocket wheels 122 on each of the upper shafts 119 and 4also passes over a pair of spaced idler pulleys 126, each of which is mounted on a stud shaft 121 ,125 in turn is powered by a sprocket chain 128 operating about a sprocket wheel 129 onV the shaft 125 and a sprocket wheel 13G mounted on the end of a shaft 131 that may be the shaft of a motor or a motor poweredgear reduction device Thus when the motor or motor driven reduction device |32 is placed into operation conveyor belts 1 1|' (Figs. 1, 4, 5 and 6) on both slicing levels Ia and |061) are placed into operation so as to convey candy in a direction reading from left to right in Fig. 1. During the time the candy is being thus conveyed a motor drive through the drive sprocket 40 (see Figs. 1 and 7) places the U-frame 29 in horizontal reciprocating motion and also places the sliding plates 34 on each leg 30 of the U-frame 29 into vertical reciprocating motion. The knife blades 96 on both levels are then placed into operation by energizing the motor 89 (Fig. l1) so that the slicer then operates to convey the continuous strips of candy into the knife blades 56 where the blades cut the strips into bar lengths and then the bars are conveyed from the blades to the discharge end of the device.

Referring now to Fig. 9 the net effect of these various motions of the U-frame, sliding plates and knife blades is diagrammatically indicated by the broken line 133. The strips of candy'are in dicated at 134 and these strips are being moved in the direction of the arrow 135 by the conveyor belts 111. In its uppermost position each knife blade 96 assumes the position shown at Qta in Fig. 9 well above the strips of candy that are being conveyed into the cutting region. As the U- frame 29 that supports each of the knife blades 9S moves from left to right at a speed corresponding to the advance movement of the candy strips |34 the knife blade 96 is moved downwardly to a position 9th where it engages the upper faces of the strips of candy. During the remainder of the travel of the U-frame the knife blade 96 passes downwardly through the candy strips 134 and since the U-frame 29 carrying each of the knife blades 96 is travelling exactly at the same rate of speed as the strips of candy 134.101 the reason hereinafter explained there is no relative hori- Zontal movement therebetween. Thus the knife blade 96 passes vertically through the candy strips and at the end of the cutting Yoperation the knife blade is lifted rapidly in a substantially vertical direction as indicated by the right hand portion of the broken lines 133 in Fig. 9. The blade is then returned to its initial raised position indicated at 96a and the operation is repeated. The relationship between the various cams, link and speeds in the instant case, of course, can be varied but it has been found that a travelling time of two-thirds of a second from a position marked A in Fig. 9 to the end of the cutting operation at B with a rapid retracting time of one-third of a second between positions B and C will give very satisfactory results.

As shown in Fig. 4 suitable guide bars 136 may be disposed relative to the conveyor belts so as to guide the candy strips and bars entering and leaving the slicer so as to prevent lateral displacement of the bars during their movement Y through the slicer.

As shown in Fig. 2 a guard bar 14!) is disposed on each side of each of the knife blades 96 and this bar includes a plurality of downwardly projecting spacer members 141 between which the strips of candy indicated at 134 pass. The spacers 14| are screwed as at 141a (Fig. 10) to a channel member 1411:, or an angle member in the case of the end spacers, which in turn is screwed as at 141e to a horizontal member 112a ofthe machine frame.

Referring to Fig. 6 a pressure device generally indicated at 142 is mounted by means of brackets 143'upon the stationary side frame members 108 and this pressure device includes a shaft |44 fixed in the free end of spaced arms 145 that are fixed to a rotatable shaft |46 in the brackets |43. Suspended from the shaft 144 are a plurality of pressure feet 141 that are free to rotate about the fixed shaft 144.

Projecting outwardly from the adjacent guard member 141] is a cam block 148 that is provided with an upper cam surface having an upper level 149 and a lower level 15G divided by an inclined surface 15|. A cam follower |52 is fixed with respect to the arms 145 and is adapted to ride on the upper cam surface of the cam stripy |48. Thus as the U-frame indicated at 29 in Fig. 6 moves from left to right the fixed cam strip |48 likewise moves under the cam follower |52. When the inclined surface 151 reaches the position of the stationary cam follower 152 the follower rides down this inclined surface to the lower surface |511, during which movement the arm 145 rotates about the center of shaft 146 so as to lower the pressure feet 141. These pressure feet 147 are so disposed that one is provided above each candy bar that is passing therebeneath and when the pressure feet are disposed in their lowermost position, that is when the lower cam surface 15S is located beneath the cam follower |52, the pressure feet |41 are engaging and bearing down on the candy bars therebeneath. In this manner proper friction is provided between the candy bars and the conveyor belts therebelow so as to eliminate all possibility of slippage of the belts beneath the candy bars. Thus when the cutting operation has been completed, in which condition the pressure feet 147 are lowered onto the candy bars, the frictional engagement of the candy bars with the conveyor belts therebelow is assured so that the candy bars are rapidly moving away from the cutting knife.
